(5) Interrupt request flag (ADIF)
(6) Internal equivalent circuit
A/D
The interrupt request flag (ADIF) is not cleared even if the contents of the ADA0S register are changed. If the
analog input pin is changed during A/D conversion, therefore, the result of converting the previously selected
analog input signal may be stored and the conversion end interrupt request flag may be set immediately before
the ADA0S register is rewritten. If the ADIF flag is read immediately after the ADA0S register is rewritten, the
ADIF flag may be set even though the A/D conversion of the newly selected analog input pin has not been
completed. When A/D conversion is stopped, clear the ADIF flag before resuming conversion.
